You have a car traveling 10m/s that speeds up to 40m/s. If it takes 4 seconds, how far does it travel during that time

d = 100 m

Explanation:

Given that,

Initial speed of a car, u = 10 m/s

Final speed of a car, v = 40 m/s

Time, t = 4 seconds

We need to find how far does it travel during that time. Let the car travel d distance. We can find it using third equation of motion as follows :

...(1)

a is acceleration and d is the distance

So, equation (1) becomes,

So, it will travel 100 m during that time.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
